Question

萨吕，

我是Weblogic WebService实现的新手。尝试使用JAX-RPC从SOAP消息中获取客户端的远程地址。需要从SOAP消息头获取客户端的远程IP。根据BEA / Oracle文档尝试了许多解决方案。 WebService java文件：

@WebService
public class clientsIPWs {
    @Control
    private SoapMessageControl smc;

    @WebMethod
    @WebResult(name="return")
    public String getClientAddress() {
        return smc.getRemoteAddress();
    }

}

SoapMessageControl.java

@ControlInterface
public interface SoapMessageControl {

    public String getRemoteAddress();

}

SoapMessageControlImpl.java

@ControlImplementation
public class SoapMessageControlImpl implements SoapMessageControl, Serializable {
    private static final long serialVersionUID = 1L;

    @Context
    private SOAPMessageContext smc;

    @WebMethod()
    public String getRemoteAddress() {
        HttpServletRequest request = 
            (HttpServletRequest) smc.getProperty("transport.http.servletRequest");
        return request.getRemoteAddr();
    }
}

在最后一个尝试使用@Context的许多变体，如MessageContext / WebServiceContext（这个不推荐使用），但是每次测试都会收到这样的异常：

无法调用结束组件无法调用方法显示java.lang.NullPointerException 在controls.SoapMessageControlImpl.getRemoteAddress（SoapMessageControlImpl.java:33）在controls.SoapMessageControlBean.getRemoteAddress（SoapMessageControlBean.java:119） at services.CustProdWs.getClientAddress（CustProdWs.java:63） at sun.reflect.NativeMethodAccessorImpl.invoke0（Native Method） at sun.reflect.NativeMethodAccessorImpl.invoke（NativeMethodAccessorImpl.java:39） at sun.reflect.DelegatingMethodAccessorImpl.invoke（DelegatingMethodAccessorImpl.java:25）在java.lang.reflect.Method.invoke（Method.java:585）在weblogic.wsee.component.pojo.JavaClassComponent.invoke（JavaClassComponent.java:99）在weblogic.wsee.ws.dispatch.server.ComponentHandler.handleRequest（ComponentHandler.java:64）在weblogic.wsee.handler.HandlerIterator.handleRequest（HandlerIterator.java:127）在weblogic.wsee.ws.dispatch.server.ServerDispatcher.dispatch（ServerDispatcher.java:85）在weblogic.wsee.ws.WsSkel.invoke（WsSkel.java:80）在weblogic.wsee.server.servlet.SoapProcessor.handlePost（SoapProcessor.java:66）在weblogic.wsee.server.servlet.SoapProcessor.process（SoapProcessor.java:44）在weblogic.wsee.server.servlet.BaseWSServlet $ AuthorizedInvoke.run（BaseWSServlet.java:181）在weblogic.wsee.server.servlet.BaseWSServlet.service（BaseWSServlet.java:92）在javax.servlet.http.HttpServlet.service（HttpServlet.java:856）在weblogic.servlet.internal.StubSecurityHelper $ ServletServiceAction.run（StubSecurityHelper.java:227）在weblogic.servlet.internal.StubSecurityHelper.invokeServlet（StubSecurityHelper.java:125）在weblogic.servlet.internal.ServletStubImpl.execute（ServletStubImpl.java:283）在weblogic.servlet.internal.ServletStubImpl.execute（ServletStubImpl.java:175） at weblogic.servlet.internal.WebAppServletContext $ ServletInvocationAction.run（WebAppServletContext.java:3244）在weblogic.security.acl.internal.AuthenticatedSubject.doAs（AuthenticatedSubject.java:321）在weblogic.security.service.SecurityManager.runAs（SecurityManager.java:121）在weblogic.servlet.internal.WebAppServletContext.securedExecute（WebAppServletContext.java:2010）在weblogic.servlet.internal.WebAppServletContext.execute（WebAppServletContext.java:1916）在weblogic.servlet.internal.ServletRequestImpl.run（ServletRequestImpl.java:1366）在weblogic.work.ExecuteThread.execute（ExecuteThread.java:209）在weblogic.work.ExecuteThread.run（ExecuteThread.java:181）

在谷歌中，几乎每个解决方案都使用了JAX-WS，这在我的框架中是不可用的。感谢。

这个解决方案对我有用：

获取HttpServletRequest / Response对象

如果您的Web服务使用HTTP作为其传输协议，则可以使用   weblogic.wsee.connection.transport.servlet.HttpTransportUtils API   获取javax.servlet.http.HttpServletRequest和   来自JAX-RPC的javax.servlet.http.HttpServletResponse对象   ServletEndpointContext对象，如以下示例所示   （相关代码以粗体显示并在示例后解释）：

 package examples.webservices.http_transport_utils;
 import javax.xml.rpc.server.ServiceLifecycle;
import javax.xml.rpc.server.ServletEndpointContext;
import javax.xml.rpc.ServiceException;
 import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
 import javax.jws.WebMethod;
import javax.jws.WebService;
 import weblogic.jws.WLHttpTransport;
 import weblogic.wsee.connection.transport.servlet.HttpTransportUtils;
 @WebService(name="HttpTransportUtilsPortType",
            serviceName="HttpTransportUtilsService",
            targetNamespace="http://example.org")
 @WLHttpTransport(contextPath="servlet", serviceUri="HttpTransportUtils",
                 portName="HttpTransportUtilsPort")
 public class HttpTransportUtilsImpl implements ServiceLifecycle {
   private ServletEndpointContext wsctx = null;
   public void init(Object context) throws ServiceException {
    System.out.println("ServletEndpointContext inited...");
    wsctx = (ServletEndpointContext)context;
  }
   public void destroy() {
    System.out.println("ServletEndpointContext destroyed...");
    wsctx = null;
  }
   @WebMethod()
  public String getServletRequestAndResponse() {
     HttpServletRequest request =
       HttpTransportUtils.getHttpServletRequest(wsctx.getMessageContext());
    HttpServletResponse response =
       HttpTransportUtils.getHttpServletResponse(wsctx.getMessageContext());
     System.out.println("HttpTransportUtils API used successfully.");
    return "HttpTransportUtils API used successfully";
   }
 }

使用JAX-RPC
